Maintenance
Most manufacturers recommend divers to have their diving watch pressure tested by an authorized service and repair facility annually or every two to three years and have the seals replaced. Besides that, simple maintenance by the owner is also important. Most manufacturers recommend rinsing the watch in fresh water after use in seawater, but leaving a diver's watch in fresh water overnight is a good method to protect the watch from corrosion and to keep the crown, buttons and pressure sensors on digital ones working.

Famous quotes containing the word maintenance:
“It is an injustice that an old, broken, half-dead father should enjoy alone, in a corner of his hearth, possessions that would suffice for the advancement and maintenance of many children.”

“However patriarchal the world, at home the child knows that his mother is the source of all power. The hand that rocks the cradle rules his world. . . . The son never forgets that he owes his life to his mother, not just the creation of it but the maintenance of it, and that he owes her a debt he cannot conceivably repay, but which she may call in at any time.”
—Frank Pittman (20th century)
“My course is a firm assertion and maintenance of the rights of the colored people of the South according to the Thirteenth, Fourteenth, and Fifteenth Amendments, coupled with a readiness to recognize all Southern people, without regard to past political conduct, who will now go with me heartily and in good faith in support of these principles.”
—Rutherford Birchard Hayes (1822–1893)
